Key legal question
Whether the cantonal rule limiting halfway release to a maximum of eleven months violated federal law.
Extracted holding
It did not violate federal law; the statute sets only the minimum fraction of the sentence to be served, not the minimum or maximum duration of halfway release.
Extracted reasoning
Art. 37 no. 3 para. 2 StGB only requires service of at least half the sentence. Federal law does not regulate the duration of the halfway-release phase; a limit of eleven months was considered sensible and permissible.
